What Is the Standard Entropy Change When 10 $\rightarrow$ CO₂(g) + 2H₂O(l)

What is the standard entropy change when 10.0 g of methane reacts with 10.0 g of oxygen?
CH₄(g) + 2O₂(g) $\rightarrow$ CO₂(g) + 2H₂O(l) $$\begin{array} { l c } \text { Substance } & \boldsymbol { S } ^ { \circ } ( \mathbf { J } / \mathbf { m o l } \cdot \mathbf { K } ) \\\mathrm { CH } _ { 4 } ( g ) & 186.2 \\\mathrm { O } _ { 2 } ( g ) & 205.0 \\\mathrm { H } _ { 2 } \mathrm { O } ( l ) & 70.0 \\\mathrm { CO } _ { 2 } ( g ) & 213.6\end{array}$$
